well that was a dumb subject matter for a youtube video
like no, eckartsladder, the clone army would not have benefited from specialised pilot gene templates. there are no biological factors that influence piloting ability that arent also relevant to a footsoldier (reaction time, eyesight), particularly one thats commonly transported via LAAT while under fire (g-tolerance and resistance to nausea)
literally everything else is training, the reason there are non clone families renowned for their piloting skills is because they passed down knowledge from an early age
